The 9601-DGS-LP is a pocket-size, low-cost, satellite tracker designed to operate with the Iridium low-Earth orbit satellite network. It is a self-contained unit relying on an internal micro-controller/GPS receiver for operation. The 9601-DGS-LP measures 4.4" x 2.1" x 1.0", weighs less than 6 ounces and can be attached to high value, un-tethered or non-powered assets such as shipping containers, barges, railcars, trailers, buoys or even to a person. It is also being used by the militaries to track environmentally demanding platforms including helicopters, fixed wing aircraft, unmanned aerial vehicles, rockets, high altitude balloons, ships, speed-boats, ground vehicles and hand-emplaced and air-deployed remote sensors.
